An ostomy appliance

Description

FIELD OF THE INVENTION

The present invention relates to an ostomy device for use with Storni. More specifically, the invention relates to a device which can be used with a base plate in a way that allows the stoma to be squeezed for longer periods and subsequently to empty the collected material without the risk of the material running out with the risk of skin damage caused by urine or faeces. .

BACKGROUND OF THE INVENTION

For certain diseases, including cancer of the colon or rectum, the bowel or parts of the bowel are removed by surgery. Then it is necessary to place either the small or large intestine in so-called ileo or colostomies, where the stool is collected in an ostomy bag. The ostomy is thus an artificially created opening on the body.

There are several different types of ostomy, the most common of which are: colostomy, ileostomy and urostomy, respectively. At colostomy, the connection to the rectum and the last part of the large intestine is disconnected and the large intestine is extended through the abdominal wall of a Storni. In ileostomy, the entire large intestine is interrupted or removed and the small intestine is discharged through the abdominal wall. In urostomy, a piece of the small intestine is used to which the ureters are attached. The other end of the bowel is passed through the abdominal wall as an ostomy.

It is known to use base plates (also called skin plates) that are glued to the skin around the ostomy. A hole is provided (or the opportunity to provide) in the skin plates for carrying the ostomy. There are various bags that can be attached to the base plate.

Eg. EP 1 795 157 A2 discloses an ostomy device for attachment to a base plate. The ostomy device comprises an attachment ring whose flange is permanently attached to the base plate. The ostomy device further comprises elements provided with means arranged to be detachably attached to the attachment ring, as well as a shield equipped with a clamping element (sealing) whereby the ostomy can be blocked. Despite the plugging element, there is still a certain risk of leakage from the stoma when not using an ostomy bag at the same time.

There are a number of disadvantages associated with the use of ostomy bags, including the user's reduced mobility and the opportunity to participate in activities (eg bathing and other activities where tight-fitting clothing is used), where it is not desired to see that the user applies an ostomy bag.

Therefore, it is therefore desirable to have an alternative to the known ostomy bag solutions.

Furthermore, it is desirable to provide a solution that allows the user not to depend on having to empty an ostomy bag for extended periods of time (for example up to six hours) and at the same time to drain the gas released to the ostomy .

The object of the invention

The object of the present invention is to provide an ostomy device which limits or completely eliminates the disadvantages mentioned above.

The object of the present invention is to provide an ostomy device that enhances user mobility, including enabling participation in activities (eg bathing and other activities using tight-fitting clothing) where it is not desired to be seen, that the user uses an ostomy bag.

It is further the object of the present invention to provide an ostomy device which allows the stoma to be closed for extended periods of time (e.g. up to six hours) and at the same time to discharge the gas released to the stoma.

The object of the present invention is achieved with an ostomy device as defined in claim 1. Preferred embodiments are defined in the subclaims and are explained in the following description and illustrated in the accompanying figures.

The ostomy device according to the invention is an ostomy device for attachment (connection) to a base plate, wherein the ostomy device comprises a detachable ring arranged for removable attachment in the base plate, wherein the ostomy device comprises additional elements equipped with means arranged to be detachably attached to the attachment ring, where the ostomy device comprises a shield equipped with a stripping element so that the stoma can be blocked / clamped, the stripping element being shaped and arranged to abut against a collection element and a distal portion of a Storni disposed therein.

This makes it possible to pinch the stoma so that the user of the stoma device can use the stoma device for periods of e.g. 2-6 hours. The stripping element is arranged to abut against a collecting element and thereby press against the ostomy which is then squeezed.

The ostomy device according to the invention can be removably attached to a base plate via an attachment ring. The ostomy device further comprises elements provided with means arranged to be removably attached to the attachment ring. These additional elements may have any suitable geometry.

The shield can be of any suitable shape. However, it may be advantageous that the shield comprises a spherical part (part of the surface of a sphere or oval structure). Advantageously, the stripping element may have a geometry which provides a predetermined pressure distribution toward the distal end of the stoma when the stripping element is brought into contact with a collection element and the distal portion of the stoma disposed therein.

It may be advantageous that the clamping element is slidably attached to the base plate.

Hereby, the degree of clamping can be adjusted by displacing the clamping element relative to the base plate, the force and thus the pressure with which the clamping element influences the free end of the ostomy is defined, inter alia, by the the distance between the clamping element and the base plate. Thus, it is possible to provide a shield with a spacer adjustable clamping element that allows adjustment of how much the ostomy is to be pinched.

It may be advantageous that the shield is symmetrical and that plugging elements are centrally located.

The shield has a convex outer surface as well as a concave side arranged to face the base plate.

It may be advantageous that the ostomy device comprises a closure disc with a thread and that the plugging element is provided with a corresponding thread adapted to be engaged with the thread of the closure disc. Hereby the clamping element can be moved up and down, so that the pressure at which the clamping element presses against the distal end of the ostomy can be varied in a simple and stepless manner.

It may be advantageous that the closure disc is provided with an internal thread extending along an inner cylinder surface and that the ostomy device comprises a plugging member comprising a cylindrical member provided with an outer (externally provided) thread extending along the outer cylinder surface.

It may be advantageous that the clamping element be centrally located on the inside of the shield. Hereby, it is possible to provide a shield with a clamping element which can be easily provided with an external thread arranged for fastening in a structure (e.g. a closure disk) with a corresponding internal thread.

It may be advantageous for the shield to cover an area extending beyond the area of the base plate where the ostomy device is attached.

In this way, the shield effectively protects the base plate and ensures that the shield adequately covers the desired area.

It may be an advantage that a cavity is provided in the central portion of the clamping element, where the cavity is arranged to receive the distal portion of an ostomy. Hereby the height can be reduced (thus the size of the shield can be reduced), as the clamping element can take up part of the ostomy to be clamped. Thus, it is possible to collect the ostomy and the collection element (e.g. a bag or condom) located around the free end of the ostomy in the cavity.

It may be an advantage that the ostomy device comprises a connecting member removably attached to the attachment ring. The use of a removably mounted connecting element makes it possible to attach and remove the connecting element e.g. in connection with the replacement of collecting elements (e.g., a condom) which may advantageously be secured in a fastening groove in the connecting element.

In a preferred embodiment of the invention, the ostomy device comprises a closure disc for attachment to the attachment ring or to the connector. This makes it possible to attach the shield to the closure disc and secure mechanical attachment to the base plate. It is preferred that the closure disk is provided with fasteners which permit removable attachment of the shield to the closure disk. Advantageously, these fasteners are adapted to adjust the distance between the closure disc and the base plate.

It may be an advantage that the closure disc comprises a flange with an internal thread as well as an adjacent portion, the flange extending perpendicular to the adjacent portion. Hereby, the ostomy can be extended through the opening in the flange and a flexible collecting element formed as a bag (alternatively a condom) may advantageously be attached to an annular fastening groove provided in a connecting element. The collecting element encloses the distal end of the ostomy and is thus capable of collecting matter from the ostomy.

It may be advantageous if the shield is provided with one or more finger grips. This makes handling the shield easier. In a preferred embodiment of the invention, the shield comprises two finger grips located at each end of the periphery of the shield.

It may be advantageous that a plurality of engagement members are arranged on the underside of the closure disk for locking engagement with corresponding apertures in an underlying connecting member or fastener ring. Hereby it is possible to provide a light attachment of the closure disc to the underlying connecting element or the underlying attachment ring.

It may be advantageous for the engagement elements to be L-shaped. In one embodiment of the invention, the engagement elements are rotatably attached to the closure disk.

In a preferred embodiment, the L-shaped engagement members comprise a central portion extending along the longitudinal axis of the closure disk and an engagement profile extending perpendicular to the longitudinal axis of the closure disk.

The washer may comprise one, two, three, four, five, six or more engagement elements. It is preferred that the engagement elements are evenly distributed along the underside of the adjacent portion of the closure disc. If the three engagement elements are used, there will be approx. 120 ° between adjacent engagement elements.

It may be an advantage that the connector or closure disk is provided with a plurality of T-shaped engagement members arranged to engage corresponding apertures in an underlying attachment ring or an underlying connector. Hereby, it is possible to provide an effective attachment of the closure disk to the attachment ring or connecting element.

It may be advantageous that the T-shaped engagement members comprise a central portion extending along the longitudinal axis of the connecting member as well as two engagement profiles extending perpendicular to the longitudinal axis of the connecting member. This type of engagement member makes it possible to rotate the closure disc, thereby placing the closure disc in various configurations, where the closure disc is respectively locked or unlocked with respect to the fastening ring or connecting element.

It may be advantageous for the engagement elements to be evenly distributed along the annular profile of the connecting element.

It may be an advantage that on the underside of the closure disc a plurality of recesses are provided for receiving upwardly projecting projections provided on the connecting member.

The number of recesses must be at least as large as the number of upward projections on the connecting element. However, the number of recesses may advantageously correspond to the number of upward projections on the connecting member. It is possible to provide a closure disc with one, two, three, four, five, six or more recesses, depending on the number of projections on the connector.

It is required that the recesses are angularly positioned / distributed in the same manner as the upwardly projecting projections on the connecting member so that the recesses can receive the upwardly projecting projections.

In one embodiment of the invention, the central portion is rotatably attached to the connecting member, whereby by means of the projections it is possible to rotate engagement members about the longitudinal axis of the central portion. Hereby it is possible to provide a very secure locking by simple mechanical means.

It may be advantageous that apertures are provided in the attachment ring each with a radially adjacent resilient structure.

Use of a resilient structure provided in connection with each opening allows tolerances to be accommodated so that the corresponding engagement elements from a connecting member attached to the attachment ring can be inserted into the openings without any problems. Furthermore, the resilient structures ensure that a locking engagement is established between the openings and the engagement elements.

In one embodiment of the invention, the resilient structure consists of a wavy profile abutting partly the opening and partly a slot allowing displacement of the resilient structure so that reception of a corresponding engaging element from a connecting element can be accomplished.

In a preferred embodiment, the attachment ring is formed with a centrally located annular disc in which three openings are provided, each provided with a radially adjacent resilient structure.

The openings may advantageously comprise a tangentially extending center structure surrounded by adjacent locking elements adapted to engage locking with corresponding engagement profiles from a connecting member mounted on the upper side of the fastening ring.

It may be an advantage that the closure disk comprises a fastening groove arranged for receiving and fastening a collecting element. Hereby, it is possible to attach a collecting element which encloses the distal end of the ostomy and is thus capable of collecting matter from the ostomy.

It may be an advantage that the fastening groove is annular and has a circular cross section.

It may be advantageous that the closure disk comprises a peripheral edge extending from the adjacent portion of the closure disk along its longitudinal axis. This provides an area in which it is possible to place an annular filter.

It may be an advantage that the ostomy device comprises an integrated filter. This makes it possible to purify the gas released from the ostomy. It may be advantageous to use a carbon filter as it will be able to purify the gas and thereby minimize the odor nuisances associated with the use of the ostomy device.

It may be an advantage that the connecting member comprises a sealing edge extending along the longitudinal axis of the ostomy device. The sealing edge may contribute to retention of matter collected in the collecting element attached to the attachment groove provided in the connecting element when the collecting element is removed from the connecting element.

Advantageously, one or more engagement profiles for handling the shield may be provided. The engagement profiles may comprise a protruding profile adapted to allow the shield to be rotated via handling of the shield by the engagement profiles.

Detailed description

Initially, it should be noted that the attached drawings illustrate non-limiting embodiments only. A variety of other embodiments will be possible within the scope of the present invention. In the following, similar or identical elements in the various embodiments will be denoted by the same reference numeral.

FIG. 1A illustrates a schematic cross-sectional view of an ostomy device 2 according to the invention before the stripping element 16 shown in FIG. 1B is attached. FIG. 1B illustrates a cross-sectional view of that of FIG. 1A in a configuration in which the stripping element 16 is secured, whereby the ostomy 20 is pinched / blocked so that no material comes out of the ostomy 20.

The ostomy device 2 is attached to a base plate 6, which is attached to the user's skin 4. The ostomy device 2 comprises an attachment ring 8 arranged for removable fastening on the inside of a fastening groove provided in the base plate locking flange 52 (see Fig. 4E). The ostomy device 2 further comprises an annular connecting member 10 attached to the attachment ring 8 via engagement members 18 arranged to engage corresponding holes / openings 42 in the attachment ring 8 (see Fig. 4A and Fig. 4B for an elaborate explanation ). The annular connecting member 10 is provided with projections 22 arranged to be received by a corresponding hole (or recess) in the adjacent portion 11 of the closure disk 12 (see Fig. 2A and Fig. 2B).

The closure disc 12 comprises a flange 14 with an internal thread 30. The flange 14 extends perpendicular to the adjacent portion 11 of the closure disc 12. The stoma 20 is extended through the opening 34 of the ostomy device 2. A flexible collecting member 28 is formed as a pouch (alternatively a condom ) is attached to an annular fastening groove 26 provided in the annular connecting member 10. The collecting member 8 encloses the distal end of the stoma 20 and is thus able to collect the material (stool) coming out of the stoma 20. The stoma device 2 according to the invention is thus capable of being used without a bag attached to the attachment flange 52. It is thus possible with the invention to use a '' bag-free ostomy device ''.

While the ostomy 20 of FIG. 1A merely surrounded by the enclosing flexible collection element 28, the ostomy 20 is clamped in FIG. 1B. In FIG. In Fig. 1B, a shield 60 is provided to the closure disk 12 consisting of a dome-shaped shell with a centrally located clamping member 16.

The stripping element 16 clamps against the collection element 28 and the ostomy 20 which the stripping element 16 encloses. Hereby the ostomy 20 is blocked, so that the user of the ostomy device 2 can use the ostomy device 2 for periods of e.g. 2-8 hours. Although in FIG. 1B appears as if a gap is provided between the back side of the stripper element 16 and the stoma 20, the backside of the stripper element 16 will, in practice, abut the collection member 28, thereby pressing against the stoma 20 which is being squeezed.

The stripping member 16 comprises an external thread 32 which fits into the internal thread 30. The stripping member 16, and thus the shield 60, is thus rotatably secured to the closing washer 12. The stripping member 16 and the shield 60 can be moved closer or further from the base plate by rotation of the shield 60. 6. A protruding profile 64 is provided at the top of the shield 60, which provides a grip that the user of the ostomy device 2 can use to rotate the shield relative to the base plate 6. Thus, it is possible to vary distances between the back of the plug member 16 and Thus, by rotating the shield 60, it is possible to vary the degree to which the back of the stripping element 16 presses against the collection element 28 and the stoma 20 so that the stoma can be sufficiently clamped.

While the ostomy device 2 squeezes the stoma 20, matter will not be able to leave the stoma 20. When the stoma device 2 is removed, the collecting element 28 will be filled with matter from the stoma 20. Thereafter, the collecting element 28 can be removed and thrown out. A new collecting element 28 can be mounted and the ostomy device 2 is ready for use again. The shield 60 comprises laterally arranged finger grips 62 for mounting a belt (not shown) for particularly corpulent users. The finger grips 62 can also be used to handle the shield 60. The shield 60 is additionally provided with a sealing member 92 arranged to seal against the underlying base plate 6. The sealing member 92 is formed as an O-ring of a circular cross section. The sealing member 92 may advantageously be made of a resilient material, e.g. rubber. The compressive cancer Ft (tangentially oriented with respect to the shield 60) pressing the peripheral portion of the shield against the underlying base plate 6 will be able to compress the sealing member 92, thereby rendering the shield 60 and thus the ostomy device 2 waterproof. As the shield 60 is screwed down over the ostomy 20, the finger grip 62 of the shield and thus the sealing member 92 are displaced radially (to the sides), thereby applying a radially oriented force Fr from the shield 60 to the sealing member 92 and the shield finger grip 62. The shield will thus be '' biased '' and able to withstand water pressure from water injected into the shield. This ensures that the shield keeps the underlying structures free of water if the ostomy device 2 is used for bathing.

The shield 60 allows the user of the ostomy device 2 to use the ostomy device 2 in connection with bathing or other activities where toilet visits are not possible.

FIG. 2A is a bottom view of a connection element 10 according to the invention, while FIG. 2E3 illustrates a perspective view of that of FIG. 2A is a top view of the connecting element 10. The connecting element 10 is formed as an annular structure with a centrally located opening. The connecting element 10 is provided with three openings 38 arranged to receive engagement elements (see Figs. 2C and Fig. 2D) from a fastening ring located below the connecting element 10. The three openings 38 are evenly distributed along the annular profile of the connecting element. Thus, there are approx. 120 ° between adjacent apertures 38. The apertures 38 are arranged to receive and fix L shaped engagement elements (see Figs. 2C and Fig. 2D) from a closure disc 12 disposed over the connecting member 10. The number of apertures 38 may vary. Thus, it is possible to provide a connecting element 10 having one, two, three, five, six, six or more openings 38. The openings 38 may advantageously be evenly spaced.

The connecting element 10 is further equipped with three T-shaped engagement elements 18 arranged to engage with corresponding openings in an underlying attachment ring receiving engagement elements (see Fig. 4A and Fig. 4B). The three engagement elements 18 are evenly distributed along the annular profile of the connecting element. Thus, there are approx. 120 ° between adjacent engagement members 18. The T-shaped engagement members 18 comprise a central portion 80 extending along the longitudinal axis X of the connecting member and two engagement profiles 78 extending perpendicular to the longitudinal axis X of the connecting member. It is seen that the connecting member 10 comprises one on the underside of the connecting member. 10 provides annular fastening profile 26 arranged for securing a collection element such as that of FIG. 1A and in FIG. 1B. Thus, it is possible to attach the proximal folded end of e.g. a condom in the attachment grooves 26 of the connecting member 10.

On the upper side of the connecting member 10, upwardly extending projections 22 are provided. These upwardly extending projections 22 are adapted to act as control elements when the connecting member 10 is to be rotated about the longitudinal axis X in connection with mounting or dismounting from an underlying attachment ring 8. The upwardly extending projections 22 may advantageously include an upright profile extending radially and along the longitudinal axis X. Hereby, it will be possible to engage a fingernail with the profile thereby providing the required torque for mounting or disassembling from an underlying attachment ring 8. The upwardly extending projections 22 may have other designs than that of FIG. 2B. The number of upwardly extending projections 22 may vary. Thus, it is possible to provide a connecting element 10 having one, two, three, four, five, six or more upwardly extending projections 22. The projections 22 may advantageously be evenly spaced. In one embodiment of the invention, the central member 80 is rotatably secured to the connecting member 10, whereby by means of the projections 22 it is possible to rotate the engagement members 18 about the longitudinal axis of the central member.

Thus, it is possible to provide a very secure locking by simple mechanical means.

FIG. 2C illustrates a top view of a closure disk 12 according to the invention, while FIG. 2D illustrates a perspective view of the one shown in FIG. 2C is a bottom view of closure disc 12. The closure disc 12 comprises a disc-shaped connecting portion 11 arranged to abut against an adjacent underlying connecting member 10 similar to that of FIG. 2A and in FIG. 2B. The closure disc 12 further comprises a flange 14. The flange 14 protrudes upwardly from the connecting portion 11. The flange 14 is cylindrical and extends along the longitudinal axis X of the closure disc. Internal thread 30 is provided along the inside of the flange 14.

On the upper side of the connecting portion 11, upwardly extending projections 36 are provided to act as a control member in connection with mounting or disassembly from an underlying connecting member 10. The upwardly extending projections 36 comprise an upright profile extending radially and along the longitudinal axis X, finger nails may be engaged with the profile to provide a sufficiently large torque for mounting or disassembly from an underlying connecting member 10.

A small gap is provided between the upper side of the connecting portion 11 of the underside of the distal portion of the upwardly extending projections 36, thereby allowing the front portion of a fingernail to be inserted into the slot so that the closure disc 12 can be raised / inserted in the longitudinal axis. direction. This is convenient in connection with removal / removal / replacement of the closing washer 12. The number of upward projections 36 can be changed. Thus, it is possible to provide a closure disk 12 with one, two, three, four, five, six or more upwardly extending projections 36. It may be advantageous that the projections 36 are evenly spaced along the adjacent portion 11 of the closure disc so that there are approx. 120 ° between adjacent projections 36.

On the underside of the closure disc 12, three L-shaped engaging elements 48 are arranged to be locked in locking engagement with corresponding openings 38 in an underlying connecting element 10 (see Fig. 2A and Figs.

2E3). The L-shaped engaging elements 48 comprise a central portion extending along the longitudinal axis X of the closure disc and an engagement profile extending perpendicular to the longitudinal axis X of the closure disc. There may be more or less engaging members 48. It is possible to provide a closure disc 12 with one, two , three, four, five, six or more engaging elements 48. It may be advantageous that the engaging elements 48 are evenly distributed along the underside of the adjacent portion 11 of the closure disc, so that there are approx. 120 ° between adjacent engagement elements 48.

Further, on the underside of the closure disc 12, three recesses 46 are arranged to receive the upwardly projecting projections 22 shown on the connecting element 10 illustrated in FIG. 2E3.

The number of recesses 46 must be at least as large as the number of upward protrusions 22 on the connecting member 10. The number of recesses 46 may advantageously correspond to the number of upward protrusions 22 on the connecting member 10. It is possible to provide a closure disk 12 with one, two , three, four, five, six or more recesses 46 depending on the number of projections 22 on the connecting member 10. It is required that the recesses 46 are angularly positioned / distributed in the same manner as the upwardly projecting 22 on the connecting member 10 so that the recesses 46 may receive the upwardly extending projections 22. In FIG. 2D, the recesses 46 are evenly distributed along the underside of the adjacent portion 11 of the closure disk. 120 ° between adjacent recesses 46.

FIG. 3A illustrates a perspective view of a closure disc 12 of the invention viewed from below, while FIG. 3E3 illustrates a perspective view of the one shown in FIG. 3A is a top view of closure disc 12.
